Application of Helicopter 3D Laser Scanning Technology in Inspection of Overhead Transmission Line
摘要:
本文介绍了直升机3D激光扫描技术，并将其应用到国网北京公司某500kV架空输电线路巡检中，通过获取的输电线路走廊的高密度、高精度激光点云和光学影像数据，实现输电线路本体及周围环境的三维建模、线路瞬时工况安全距离检测、线路不同工况安全距离分析以及平断面图输出，进而给出实时工况安全距离危险点分析报告，为线路安全维护提供可靠信息。
Abstract:
This paper introduces the technology of helicopter 3D laser scanning and the application to the inspection of a 500kV overhead transmission line in Beijing. By obtaining high density, high precision laser point clouds and optical image data in the transmission line corridor, it can realize3D modeling, safety test of line instantaneous under working condition, safety distance analysis under different working conditions and output of plane section, of transmission line and surrounding environment. Then the risk point report of the safety distance analysis under real time working condition is given, which provides reliable information for the maintenance of line safety.
